MIAMI (CBSMiami) – A South Florida hospital is giving its employees a new start at life as well.

After her first son was born, Lymaris Diaz went from 145 pounds to 239.

“When I saw pictures I thought, oh my god I can’t believe I let myself get this big,” said Diaz. “I saw myself addicted to food. I couldn’t let go of it. I would wake up in the middle of the night to eat. I said I have to change.”

Thanks to a program at her job; she could make that change. Lymaris works for Miami Children’s Hospital. Last year, they started a program for its employees called “Lose To Win.”

The participants workout with a trainer twice a week, and meet with a dietitian once a week during the six month program. Lymaris was last year’s winner. She won weighing in at 163 pounds. Porfirio Ramirez won second place after losing 86 pounds.

Yes, they have trainers, dietitians, nurses that oversee their progress, but there’s no shortcuts in this competition.
